I remember once someone told me that if you chew bubblegum and accidentally swallow it your tummy would blow up and it was only since last year I realized that wasn't true.
A childhood belief about chewing gum

others believed things like this
- When I was a kid My friend’s mom told me if I swallowed my bubblegum it would make me fart bubblegum bubblesAnon
- I thought i had to chew my food 27 times before i could swallow because Stephanie said it on Full HouseAnon
- I was told that if you chew your hair you end up with a hairball in your stomach and DIE!!!!!— Cat
- i was told when i was young that if i swollowed gum my stomach would grow teeth to chew it— gammie
- I used to think that if you didn't blow your nose and just sniffed the snot up, you head would blow up.Anon
- I used to think that if you ate cat food you would die. I found out it wasn't true
